If you are looking for a good hard drive to upgrade your PS4 look no further, this is the one you need (5400RPM is recommended, and the drive needs to be 2.5 inch)
When I purchased my PS4 when it first came out, the unit that came in my PlayStation 4 500GB Best Buy Bundle. At the time I thought it was too much and that I would never see the day I'd run out of space. Well, after downloading all kinds of things from the PSNetwork (videos, dlc, games) the day finally came several months ago. I backed up as many things as I could on external drives but dlc and game installs kept using disk space until I was left with about 3 free gigs. With the price of the drives compared to a new PS4 it was a difficult decision, especially since there was a 1TB Hybrid SD HD that I was thinking of purchasing.
After some research on the size of the drives, maximum capacity of the PS4 and other related topics, I ended up finding this drive in Amazon. After reading some of the reviews here I decided I would go for the 2TB drive. While I was researching on the web, I found a lot of different stories and assumptions on whether or not the fat PS4 was capable of handling a 2TB drive as well as some reports indicated formatting the drive would take between 14 to 60 hours!
So this is how it went for me: I backed up the PS4 data using the Backup feature under System Tools, it took about an hour and a half to backup a little over 60 gigs. Removing the hard drive and replacing it could not have been easier (I struggled a little finding the right screwdriver though) and it took about less than 5 minutes; there are plenty of videos available in you tube that tell you how to do this. Once replaced, I started the PS4 and it immediately asked me to format the drive (I installed the drive out of the box), it literally took less than a minute to format a 2TB drive! After that, I went to system tools and restored my backup from my external drive, another hour and a half. So, as another reviewer confirmed, it took less than four hours to upgrade both hardware and software.
Results so far have been great, I immediately started downloading more games and demos, space is no longer an issue! (for now, I guess) The PS4 does recognize the 2TB capacity as opposed as to what many websites indicated.
For those concerned about the brand I would suggest you play it safe and go with Seagate, the original 500 gig drive I removed from my PS4 was a Seagate as well, no issues whatsoever in the four years I used it! Another happy upgrade!
Hopefully there will be 3 or 4TB drives in the near future then it will be another happy upgrade!
